To all 'whom t may concern:

Be it known lthat LMAX KAMAN, a citizen of the United States, residing at Rochester, in the county of Monroe and State of 5. New York, have invented certain new and useful Improvements in Radiators, of which the following is a specication. n

This invention relates to improvements in radiators,I of the class employed for cooling the water which protects the cylinders of automobiles and other internal combustion engines, and has for its object to provide a radiator' structure which is novel, simple and effective, wherein a given quantity i of water may be readily and quickly cooled,

and wherein the amount and weight of the metal employed in the structure are greatly reduced, thereby lessenin'g the cost of construction, kand still producing a radiator which is durable and which has greater flexibility and strength for withstanding the vibrations of the engine, than any other device of the class 'known to me. ther object is to provide a radiator of the 25 class which is sectional, and wherein each section is capable of being applied, removed or replaced, without disturbing theother sections.

I attain these objects by the means set A:torth in the detailed description which follows, and as illustrated bythe accompanying drawings, in which- Figure 1 is a front elevation of the complete radiator. Fig. 2 is an enlarged horizontal sectionv taken on line 2-2 of Fig. 1. Fig. 3 is an enlarged vertical transverse section taken on line 3-3 of Fig. 2. Fig. 4 is an enlarged central vertical cross section -fr'taken"substantially on line 4 4 of Fig. 1. Fig. 5 is an isometric view; showing the construction and' arrangement of the air iiues and channels that interlock the tiers of each section. Fig. Gfi's an enlarged broken horizontal section taken on line 6 6 45. of Fig. 3. Fig. 7 is an enlarged broken vertical section taken on line 7-7 of Fig. 3. Fig. 8 is a perspective view of one of the V channels. And Fig. 9 is a perspective lview 'of one of the air tubes.

' ing the motor cylinders (not shown) is sup;

plied, 6 lrepresents a pipe which conducts the hot water to the top ofthe radiator, and'? represents a4 pipe through which the cooled water is returned from the bottom of the radiator to the motor jackets. The

hot water` delivered to the to of the radio ator, as explained, in gravitatmg to the bottom of the body 2, passes between and around a relatively large number of tubes or lues 8, which are grouped together, preferably in regular vertical and horizontal tires. The tubes 8 are preferably disposed horizontally and they are also preferably spaced equi-distantly in all directions, as shown. The tubes 8 are preferably square and have clear openings throughout for the free passage or circulation of the air, which is the cooling agent. In the preferred form,

the tubular portion of my radiator is preferably arranged in several sections, as 9, 10,

11, and 12, which for convenience in constructing, assembling, and repairing'are disposed horizontally, and these sections are l placed 'one above the other until the re- 80 quired cooling eld is provided. The vertical and horizontal water'spaces between the tubes 8 of each section may'vary in size to suit different conditions, but I prefer a uniformandfclearspacing of one-sixteenth to one-eighth inch between the adjacent tubes. During the cooling operation, the Water gravitates from the top to the bottom 'of the tank 2 mainly through the vertical spaces 13, but the water also iills the horizontal spaces 13', so that there is a complete 'shown in Figs. 1 anda, they together com- 95 prise asingle radiating field, as there are no barriers or partitions between the iues of After the water has been cooled as described, it is collected in a clear space 2 in the bottom of the body 2 from which it discharges through the. pipe 7.

The tubes 8 are` preferably made of relatively thin brass and drawn square, and their opposite ends are slitted longitudinally at the four corners a sufficient distance to permit the to and bottoml sides or Webs to be folded bac ardupon the bodies of the tubes for providing similar hook-fiangcs 1lb-14.. In like manner, vthe opposite lateral sidesare folded backward to the Same 110 sectionsmay be readily otherwise would occur between 1G- 16' of the adjacent vertical tiers.

- and channels. l placed one above the other,

extent, for providing similar hook-flanges 15-15 (see Figs. 2, 5, 6, 7, and 9). The bottoms of the lowermost tiers of tubes, and also the tops of the uppermost tiers of tubes of the adjacent sections, are provided with vertically arranged flanges 16`16, instead of the hook-flanges of the other tubes, and these flanges 16-.16 are arranged to overlap each other (see Figs. 3, 4, and 5) for interengaging the sections. The fianges 16-16 are preferably disposed about one-eighth of an inch inwardly from the opposite ends of the tubes, so as to provide a sort of trough extending horizontally across the face of thel radiator, the said trough being finally filled with solder 17, for effecting a watertight and rigid joint between the sections. The

and quicklyseparated by removing the solder 17. When the tubes 8 are assembled, the tubes of each vertical tier are placed one above the other, with the hook-flanges` -14 registering with and resting upon the flanges 14 of the adjacent tubes. The flanges 1st-14e serve as the gages for the horizontal water spaces 13. In like manner as the tubes are placed in position the lateral hook-flanges 15-15 are brought together and form or gage the vertical Water spaces 13. The several rows or tiers'of tubes 8 of each section are locked and .held together by a number of channel-shaped stays or parts 18, which are disposed vertically, two of said stays being-placed between each pair of adjacent tubes of the vertical tiers (see Figs. 2, 3, 5, and 7). The channels 18 are preferably formed-up substantially the width of the vertical water spaces 13, and arel inserted between the opposite ends of the tubes with their hollow sides facing outwardly, so as to receive and grip Vthe lateral hook-flanges 15-15, as shown.

The channels 18 are preferably slightly longer than the depth of each section, so that the ends of the corresponding channels meet about midway in the horizontal space (17) between the adjacent sections, as at 18 in Fig. 3. By this arrangement, the channels 18 substantially close the gaps which the flanges After all of the tubes 8 and the channels 18 of a. section are assembled, as described, the front and rear faces of the sections are dipped in melted solder which solidly unites all of the parts as one, and effects a water-tight seal of all ofthe joints between the several flanges Then as several sections are the troughs occurring between the sections are filled with thesolder 17, as explained. The vertical t1ers of tubes may be readily separated by runnlng a hot soldering iron over the joints formed by the-channel stays or by directing the flame of ablow-.lorch against said joints and then injured or leaking tubes may be turbing the removed, repaired or replaced without disother tiers or tubes.

The tubular, portion of the radiator may be secured to the frame or casing 2 in an suitable manner, as by vertically and hor1- zontally disposed strips 19-19 which may be fastened to the respective parts by solder or by any other usual means.

My improved radiator is extremely simple, and owing to the number and close arrangement of the flues 8, it is capable .of readily and eifectually cooling the water it receives from the motor cylinders.

Th provision of the large number of radiating tubes 8 which are'arranged to divide the body of hot sheets or columns, ali'ordstlie maximum amount of radiating service without increasing the size of the radiator. The grouping and arranging of the flues 8 into sections of convenient size, each of which are readily detachable without disturbing the adjacent sections in case of of the tubes, greatly enhances the value of my improvement. And furthermore, by the novel provision of the hook-flanges 14 and 15 and the channels 18, as Well as the flanges 16, all of which coperates for interfitting and interlocking the parts together, enables me to construct my new radiators of relatively light weight metal and still produce a strong and durable device. By the pro-v cost of the radiators. It is obvious that the hollow tubular por` tion of the radiator may be made in one part by extending the channels 18 the full depth of the radiating field without departing from thel spirit of the invention.`

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

1. In a sectional radiator, the combination with a plurality of sections, each section comprising a plurality of square tubes arranged in vertical and horizontal rows, the opposite ends of each tube having hookanges disposed .on the top and bottom sides,
